art. Secured to the-underside of the'lay 51 at opposite ends thereof are two'U-shaped brackets 12, 12 and through each of these brackets passes a guide rod 13 secured therein andhaving mounted thereon a slide 14 preferably. formed of oil impregnated Wood. Secured to the slides 14, 14 in any suitable manner are cushions or pads 15 preferably forined'of leather, said cushions being also secured to a flexible member 16 preferably consisting of a leather Strap which extends from side to side of the loom and is-secured at its opposite ends to the outer ends of the brackets 12 by nuts 17 having screwtlireaded'engagement with the guide rods subject of the King of Denmark, residing the county'of Suffolk and State of Massachusetts, have invented new and useful Improvements in'Slnittle-Check- This invention relates toimprovements gradually checking the speed of the box anu preventcreasing the power necessary to throw the of guides preferably conslstlng of a series of leather loops 18 secured to the lay 5 and said strapisof such a length as to form a slack alternately at opposite ends thereof when reciprocatcd through the loops 18, the appearance of this slack being shown in Flg. 3, which illustrates theleft hand end of the strap.

When the left hand picker stick 10 has propelled the shuttle 9 toward the right, said picker stick returns into contact with the cushion 15, as shown in Fig. 2, and when the shuttle is propelled by the right hand picker stick toward the left into (the left hand box 8, said shuttle in str1k1n g the picker causes the left hand picker stlck 10 to more the cushion 15 and slide 14 toward the left, thereby carrying the strap 16 fromthe positionshown in Fig. 2 into the position shown in Fig. 3, during which movement the strap slides through the loops 18 and owing to the inertia of the strap 16, cushion 15 and slide 14 the speed of the picker stick and consequently-the speed of the shuttle i gradually checked so that the shuttle comes to a state'of rest in the'box without rcbound,- the action being quite similar to the action which takes place when a ball is caught in the hand of a person. It will .be understood that the weight of the -.strap will be properly proportioned to the weight of the shuttle, it being evident that a h'eavy shuttle will require a heavy strap and a light shuttle a correspondingly light strap. It will be evident that the movement of the strap 16 toward .the left as just described shuttle strikes when entering the box.

The invention consists in the novel feaparticularly pointed out in the appended claims.

Referring to the drawings: Figure 1 is a cross sectional view of a portion of a loom embodying my invention, the same being. partly broken away to save space in the drawings. Fig. 2 is an enlarged detail plan section taken on line 22 of Fig. 1, show ing a portion of the picker stick checking strap in its righthand position. Fig. 3 is stick checking strap in its left hand position. Fig. 4 is a. sectional View taken on line 4- l of Fig. 1, looking toward the'right.
